CHARLES M. BURGESS, OF NE'W BRITAIN, CONNECTICUT, ASSIG-NOR TO THE RUSSELL (it ERVVIN MANUFACTURING COMPANY, OF SAME PLACE.

SASH-FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 333,337, dated li iarch 23, 1886.

Application filed January 18, 1886. Serial No. 189,001. (No model.)

To all whom it .may concern:

Be it known that 1, CHARLES M. Bnncnss, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification. My invention relates to improvements in that class of sash-fasteners which are designed for use upon meeting-rails of sashes; and the object of the invention is to lessen the cost of production by so forming the parts that they may be cast in an ordinary two-part flask, with the screw-holes complete,without coring,

i5 and so that two pieces of casting and a spring will form a complete sash-fastener, less the keeper.

In the accompanying drawings, Figure l is a front elevation of my sash-fastener. Fig. 2 is a side elevation. Fig. 3 is a rear elevation.

Fig. 4 is a plan View of the frame of my sashfastener, the same being represented as tipped over into the position in which it is cast. Fig. 5 is a transverse section of the same on line 00 0c of Fig. 4. Fig. 6 is a transverse section of the same on line y y of Fig. 4, and Fig. 7 is a side elevation of the sweep and pivotalpost.

A designates the frame of my sash-fastener, 0 the same consisting of a base-plate, a, having screwholes b b, an upper bearing-plate, c, and a vertical plate, d, which connect the base and upper bearing plates. This connectingplate is chambered or recessed upon its inner 5 side for the reception of the flat sheet-metal spring f. The vertical plate at is provided with an opening in the middle of its length, and leading therefrom is an opening in both of the plates (1 and c, the rounded sides of which form the upper and lower bearings for the journals of the pivotal post B. The upper bearing-plate, 0,-instead of being'made horizontal, is made to slant upward toward the front, whereby the frame when placed in the position represented in Figs. 4, 5, and 6, can be molded in an ordinary two'part flask with out coring; and may be cast with the journalrecesses, the screw -holes, and the spring-recess, all complete in the form shown. The pivotal postB may be provided with any or- 5 namental. tip at its upper end. a square hub, {1, near its lower end, and with journals h h, both above and below said square hub, while the ordinary sweep or hand lever C extends from one side of the squared hub at a point between the journals ll, h. These parts, as shown in Fig. 7. are integral, the same being cast in one pieceot' metal. Afterthe castings are obtained it is only necessary to pass the sweep or handle lever C through the middle opening of the frame and then bring the bearings h h of the pivotal post B into the journal-recesses of the plates (1 and c, and then insert the springf within the spring-recess with its middle portion bearing upon the back side of the squared hub, so as to continually hold the pivotal post against the rounded side of the journal-recesses.

The operation of the parts when assembled is the same as in prior sash-fasteners.

The keeper for use with this sash-fastener is of ordinary construction.

I am aware that sash-fasteners have been heretofore made with the sweep or handle lever having a squared and flanged post that projected below the sweep,and which was inserted vertically into a vertical hole in the case or spring-box and held therein by a spring or springs, substantially as in the patent to Burgess and Sanford No. 234,387, November 16, 1880, and the same is hereby disclaimed.

I claim as my invention- 1. In a sash-fastener of the class described, the frame A, consisting of the horizontal base-plate a, the upper bearing-plate, a, slanting forward and upward, as shown, and the connecting vertical plate (I, said plates being recessed from the back side, for the reception of the pivotal post, substantially as described, and for the purpose specified.

2. The pivotal post B, having squared hub g,and the sweep or handle lever C, all formed in one piece and with the journals h h, formed 5 at points above and below the said handle lever, substantially as described, and for the tegral hand-lever O, and the springf, all subpurpose specified. stantially as described, and for the purpose 3. The sashlock herein described, consistspecified. ing of the frame A, having its upper bearing- 5 plate slanting forward and upward, the said \Vitnesses:

frame having '0nrnal-recesses opening at the THOS. S. BISHOP, back side thereof, the pivotal post B, and in l M. S. VIARD.
